EDMUND BRUDER, or CHICAGO, ILLINOIS, ASSIGNOR To HAROLD r. KoieieaLli/IM;` OF

WILMETTE, ILLINOIS.

DISPENSER.

To all whom t muy concern.' l l Be it known that l, E DMUND` BnUnnn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain nerv and useiul Improvements in Dispensers, of which the following is a specification.

This invention relates, todevices of' the class typified by liquidsoap. dispensersl` `the objects of the invention being to produce a dispenser which shall not bev liable to get out of order, nor be readily tampered with, andivhich shall effectively prevent dripping When the valve is closed.

ln the accompanying drawings, Figure 1 is a fragmental sectional view et a dispenser embodying the features of my invention. Fig. 2 is a sectional. view taken in the plane of dotted. lines 2,-.-2 of Fig. 1. Figs. 3 and i1 are 'tragmental sidevieivs ot' the body of the dispenser. Fig'. 5 is a sectional vievv taken in the plane of dotted line 5 5 of Fig. 2. Fig'. 6.is.a section on line 6-6 of Fig.

Fig. 7 is an inner side view of the rotatable valve member. Fig. 8 is a section on dotted line 8-.8 of Fig'. 3. v

lThe embodimentl herein shown of the invention comprises a bracket 1 which ma;Y be of any suitable lorm and having any pre.- ferred means for attaching the bracket to a Waller other suitable support. integral with the Yforward end of the bracket `l is a socket 2 in whichl is secured the loiver end oi a container 3. Below the socket 2 is located' the body il of the dispenser. ln one end of the vbody 4 is formed an axial chamber that contains an oscillatory Yalvc member for cont-rolling the How of soap. in the opposite end of thebodiv 41 is in'ovided a chamber 6, one halt of the chamber being 'Formed of a recess in the body 41 and the other halt being'formed of a recess in a plug,r 7 that' is screwed into an axial internally-threadedfsoeliet 8- in the body. The chamber 6 is provided with an elastic diaphragm or Wall 9 which may consist of a sheet of rubber, said sheet being` herein shown as secured in1 place by having its margin clamped between the inner end Wall of the recess 8 and the inner side of the plusr 7. The space in the chamber 6 at the outsideof the diaphragm 9 communicates with the atmosphere by means oi one or more ports 10.

An axial port `11 extends from the. space Specification of Letters Patent.

within the chamber (i at the inner side of the diaphragm 9 to the inner end wall oft' the chamber 5. 12 is a supply duct leading downward from the socket and opening upon the inner end Wall oi. the chambenwi. A. discharge duct 13 extends from the inner end Wall 'of the chamber 5 to a disrluirgc nozzle 1l. The function of the valve member hereinbefore mentioned is to connect the chamber 6 alternately with the ducts 12 and 13. Said valve member is indicated at 15 and consists of a disk fittiirg` within the chamber 5 in Contact with the inner end Wall of said chamber. In theinner face of the valve member 15` is a groove 16 extending from the axis oir' the valve member to a point adapted to register withV the'loiver end oi' the supply duet 12 Qrtlie upper end of the outlet duct 13, depeni'ling upon the position of the valvemember. i

The meansv for oscillating thevalve member 15 comprises a lever having` the `general iorm oit a bail and comprising-two arms 15T and 1S and a connecting portion or crossf piece 19. For convenience in manufacture. one half of the crosspiece 19 may be formed integral with each of said arms] Herein is shown adoivel pin 2O assistingr'to connect the tivo halves of said crosspieuie.V The upper ends oit' the arms 17 and 18 lit pivotallyv Withinthe outer ends oit the chamberf and the recess 8, respectively. 2lv is a ductentending through the pivot portion oi'4 thearm V18 to permit atmospheric pressure to be exerted upon the diaphragm 9 through the ports'- 10. `The arms 17 audflS are rieiiilly connected together by means of' a screiv Q2. The head 23 of thescreiv Qi?, is preferably concealed by countersinliinp; the bead in the arm 17 and filling the counter-sink Hush with the surface ott-he arm 1? with a substance adapted to be nickel -plated together `with y `the remained of the arm. Y

The means for (.'onncctingr the valve men'iber 15 to the lever comprises a tongue Q1' (Figr. 2) formed integral with the pivot portion of the arm 17 and extendinginwardly there from. said tongue fitting into a slot "or groove 25 (F ig. 3) `formed inthe stem 26,01l the valve member 15.

The meansiOr pressing` the valve member 15 against its seat, i. e., theinner end Wall of the chamber 5, to prevent leakagelot soap, and for normally holding the valve member in closed position, comprises a. coiledtorllll' sion and expansion spring 27 (Fig. 2) secured at one end to the valve member 15 and at its other end to a disk 2S having a hub 29 in which the stern 26 is rotatably mounted. The disk 28 is rigidly secured Within the chamber 5 in any suitable manner. Herein'the disk is shown as provided with two dametrically opposite notches 30 to receive studs 31 projecting inwardly from the wall of the chamber 5. The disk 28 is provided With two diametrically opposite notches 32 adapted to pass the studs 31, so that the disk 28 may be inserted into the chamber 5 with the notches 32 in register with the studs 31. After the disk has been inserted beyond the studs 31, it may be turned to bring the notches 30 into register with said studs. The spring 27 holds the disk 28 pressed against the studs 31.

The parts normally occupy the position shown 1n Figs. 1 and 2 and the full-line position shown in Fig. 5. The chamber 6 1s then in communication with the interior of the container 3 through the supply duct 12, the groove 16 and the port 11, as shown in Figs. 5 and 6. i The weight of the soap will distend the diaphragm 9 into the posltion shown in dotted lines in Fig. 2. When it is desired to discharge soap, the user presses his hand against the crosspiece, thereby swinging said crosspiece rearwardly and upwardly into the position shown in dotted lines in Fig. 5 and bringing the hand of the user beneath the discharge nozzle 14. The valve 15 is thereby turned to carry the ve 16 out of register with the supply gigli 12 (thus cutting loii' communication between the container 3 and the chamber 6), and bringing the groove 16 into communication with the discharge duct 13. Thereupon soap flows from the chamber 6 through the port 11, the groove 16and the discharge duct 13 into the hand of the user. When the `user withdraws his hand, the spring 27 aids gravity in returning the lever and the valve 15 to normal position, thereby interrupting communication between the chamber 6 and the discharge duct 13 and reestablishing communication between the container 3 and the chamber 6.

`In the present embodiment of the invention, the swinging movements of the lever are limited by contact of the screw 22 with the side of the discharge nozzle 14 and the lower side of the bracket 1, as indicated in Fi'g.` 5,'but anyA other suitable means may be employed for this purpose.

It will-be understood that the construction herein shown is applicable also to the dispensing of soda-'fountain sirups, the leverV being operable in the act of placingr a glass or othe receptacle beneath the discharge nozzle 14. Other Vuses will doubtless suggest themselves, and hence the invention is not to be limited to the dispensing of any particular kind of liquid, nor to the particular construction herein illustrated except .to the extent indicated by the ap ended claims.
